UIButton insets - Title below image

- (void)fixTitleAndImageInsetsForButton:(UIButton *)btn {
	
	// the space between the image and text
	CGFloat spacing = 6.0;
	
	// lower the text and push it left so it appears centered
	//  below the image
	CGSize imageSize = btn.imageView.image.size;
	btn.titleEdgeInsets = UIEdgeInsetsMake(0.0, - imageSize.width, - (imageSize.height + spacing), 0.0);
	
	// raise the image and push it right so it appears centered
	//  above the text
	CGSize titleSize = [btn.titleLabel.text sizeWithAttributes:@{NSFontAttributeName: btn.titleLabel.font}];
	btn.imageEdgeInsets = UIEdgeInsetsMake(- (titleSize.height + spacing), 0.0, 0.0, - titleSize.width);
